Did this with 400, 600, and 800 grit sandpaper. Doesn't look like a mirror, but feels as smooth as glass now, and the truck feels a little better. It caused my check engine light to come on, but just cleared it with the Predator. It stated "Incorrect reading of MAF sensor". Works great now, but all of a sudden, I started to get a little knock from the motor. Put in higher octane gas 93 vs. 91, and now the knock is gone. I guess that this must have actually helped increase airflow into the motor. I never needed more than 91 octane with the predator until I did this mod, but now with 93 octane the truck feels better.

Hey, could you tell a big difference with the Volant/Ram Air intake? Especially on cold nights.

 

Cold nights, its awesome, surprizing on how much you can feel with just an intake!
